HEINRICH HENRIGH, OF NEW YORK, N. Y.

FINGER-RING.

SPECIFICATION forming part of Letters Iatent No. 293,875, dated February 19, 1884.

Application filed December 8, 1883. (No model.)

' To all whom, it may concern:

' New York, and a citizen of the United'States' Be it known that I, HEINRICH H NRIcH, of the city of New York, in the county and State of of America, have invented a new and useful improvement in finger-rings and other articles of jewelry in which stones are set, of which the following is a specification.

My invention relates to the setting of a stone in articles of jewelry; and it consists in the devices herein described and claimed, whereby the stone may be conveniently removed from and replaced in its setting without ma'rring or disturbing the structure of the same.

Inthe drawings, Figure 1 is a perspective view of the crown-piece or head of a fingerring in which astone is set,and showing a detached part of the hoop. Fig. 2 is an inner face view'of said head. Fig. 3 is a reversed View with the plate forming the inner wall of said head removed. Fig. 4 is a face view of said plate. Fig. 5 is a crosssection of the said head with detached portions of the hoop. Fig. 6 is a view similar to Fig. 3, showing a modification thereof, relating to the screw attachment of said plate to the frame of the head; and Fig. 7 is an end view of Fig. 6,. showing also the stone in place in its setting.

A is the frame or. shell of the crown or head, formed of a bottom plate, a, curved to fit-to the finger of the wearer, .as' shown, and from the edges of which project'the side and end walls, I), of the shell, the outer edges of which are provided with a dovetailed rabbet, 0, into which the stone" B, having inclined edges, is fitted, forming with said rabbet a dovetailed joint, asshown. The end wall at one end of the head being cut away above the bottom of the rabbet, the stone may be slid into its place in the head from that end. a G is a detachable plate fitted to slide into said head, entering at the same end at which the stoneis introduced. Its beveled edges-fit into the angle formed by the inclined sides of the shell and the projections d, that form the bottom of. said rabbet. This plate G is provided at its outer end with a flange, e, the side edges of which project above and below the faces of the plate, and the part above the plate is inclined inward, so as to fit into the beveled edge of the stone B, thus completing the dovetailed joint entirely around the stone. This plate is detachably held in place in the head by a screw f, which passes through a hole, f, in the plate a into a screw-threaded hole, f in the plate 0, as seen in Fig. 4. The

stone may be taken out by simply removing said screw, withdrawing plate 0, and then drawing out the stone endwise' from its setting and replaced or another inserted by re-- versing the movement. The hole f should be countersunk, and the screw f provided with a tapering head fitting into said countersink.

Instead of placing the fastening-screw at the place indicated in Figs. 2, 3, 4, and 5,. screwthreaded sockets g 9 may be provided in the end corners of the frame or shell A, as shown in Figs. 6 and 7, and fastening-screws passed into them through holes in the flange e.

I have described my invention as applied to a finger'ring; but it is obvious that it may be equally well applied to any article of j ewelry in which ornamental stones are set.

What I claim as my invention, and desire to secure by Letters Patent, is-

Afinger-ring or analogous article of jewelry containing a stone-setting wherein is combined the frame A and detachable plate 0, retained in place in said frame by a removable screw, as and for the purpose described.
